All Implemented Interfaces:

Direct Known Subclasses:
  CommonsPathMapHandlerMapping

Deprecated. as of Spring 2.5, in favor of annotation-based request mapping. To be removed in Spring 3.0.

    public abstract class AbstractPathMapHandlerMapping

extends AbstractUrlHandlerMapping

Abstract implementation of the HandlerMapping interface that recognizes metadata attributes of type PathMap on application Controllers and automatically wires them into the current servlet's WebApplicationContext.

The path must be mapped to the relevant Spring DispatcherServlet in /WEB-INF/web.xml. It's possible to have multiple PathMap attributes on the one controller class.

Controllers instantiated by this class may have dependencies on middle tier objects, expressed via JavaBean properties or constructor arguments. These will be resolved automatically.

You will normally use this HandlerMapping with at most one DispatcherServlet in your web application. Otherwise you'll end with one instance of the mapped controller for each DispatcherServlet's context. You might want this -- for example, if one's using a .pdf mapping and a PDF view, and another a JSP view, or if using different middle tier objects, but should understand the implications. All Controllers with attributes will be picked up by each DispatcherServlet's context.

Constructor Detail

### AbstractPathMapHandlerMapping

    public AbstractPathMapHandlerMapping()

  Deprecated.

Method Detail

### setAutowireModeName

    public void setAutowireModeName(String constantName)
                             throws IllegalArgumentException

  Deprecated.
  Set the autowire mode for handlers, by the name of the corresponding constant in the AutowireCapableBeanFactory interface, e.g. "AUTOWIRE_BY_NAME".

  Parameters:
    `constantName` - name of the constant
  Throws:
    `IllegalArgumentException` - if an invalid constant was specified
  See Also:
    `setAutowireMode(int)`, `AutowireCapableBeanFactory.AUTOWIRE_BY_NAME`, `AutowireCapableBeanFactory.AUTOWIRE_BY_TYPE`, `AutowireCapableBeanFactory.AUTOWIRE_CONSTRUCTOR`, `AutowireCapableBeanFactory.AUTOWIRE_AUTODETECT`

### setAutowireMode

    public void setAutowireMode(int autowireMode)

  Deprecated.
  Set the autowire mode for handlers. This determines whether any automagical detection and setting of bean references will happen.

  Default is AUTOWIRE_AUTODETECT, which means either constructor autowiring or autowiring by type (depending on the constructors available in the class).

  Parameters:
    `autowireMode` - the autowire mode to set. Must be one of the constants defined in the AutowireCapableBeanFactory interface.
  See Also:
    `AutowireCapableBeanFactory.AUTOWIRE_BY_NAME`, `AutowireCapableBeanFactory.AUTOWIRE_BY_TYPE`, `AutowireCapableBeanFactory.AUTOWIRE_CONSTRUCTOR`, `AutowireCapableBeanFactory.AUTOWIRE_AUTODETECT`

### setDependencyCheck

    public void setDependencyCheck(boolean dependencyCheck)

  Deprecated.
  Set whether to perform a dependency check for objects on autowired handlers. Not applicable to autowiring a constructor, thus ignored there.

  Default is "true".

### initApplicationContext

    public void initApplicationContext()
                                throws BeansException

  Deprecated.
  Calls the `detectAndCreateHandlers` method in addition to the superclass's initialization.

  Overrides:
    `initApplicationContext` in class `AbstractHandlerMapping`
  Throws:
    `ApplicationContextException` - in case of initialization errors
    `BeansException` - if thrown by ApplicationContext methods
  See Also:
    `detectAndCreateHandlers(org.springframework.beans.factory.config.ConfigurableListableBeanFactory)`

### detectAndCreateHandlers

    protected void detectAndCreateHandlers(ConfigurableListableBeanFactory beanFactory)
                                    throws BeansException

  Deprecated.
  Look for all classes with a PathMap class attribute, instantiate them in the owning ApplicationContext, and register them as MVC handlers usable by the current DispatcherServlet.

  Parameters:
    `beanFactory` - the ConfigurableListableBeanFactory to register the created handler instances with
  Throws:
    `BeansException` - if handler detection or creation failed
  See Also:
    `PathMap`, `getClassesWithPathMapAttributes()`, `AutowireCapableBeanFactory.createBean(java.lang.Class)`, `SingletonBeanRegistry.registerSingleton(java.lang.String, java.lang.Object)`

### registerHandler

    protected void registerHandler(PathMap[] pathMaps,
                                   Object handler)
                            throws BeansException,
                                   IllegalStateException

  Deprecated.
  Register the given handler for the URL paths indicated by the given PathMaps.

  Parameters:
    `pathMaps` - the PathMap attributes for the handler class
    `handler` - the handler instance
  Throws:
    `BeansException` - if the handler couldn't be registered
    `IllegalStateException` - if there is a conflicting handler registered

### getClassesWithPathMapAttributes

    protected abstract Class[] getClassesWithPathMapAttributes()
                                                        throws Exception

  Deprecated.
  Use an attribute index to get a Collection of Class objects with the required PathMap attribute.

  Returns:
    a array of Class objects
  Throws:
    `Exception`

### getPathMapAttributes

    protected abstract PathMap[] getPathMapAttributes(Class handlerClass)
                                               throws Exception

  Deprecated.
  Use Attributes API to find PathMap attributes for the given handler class. We know there's at least one, as the getClassNamesWithPathMapAttributes method return this class name.
